This page covers settings that control Information Lifecycle Management (ILM) for the AIStor process. You can establish or modify settings by defining: an environment variable on the host system prior to starting or restarting the AIStor Server. Refer to your operating system’s documentation for how to define an environment variable. a configuration setting using mc admin config set. If you define both an environment variable and the similar configuration setting, AIStor uses the environment variable value.

AIStor’s Object Lambda enables developers to programmatically transform objects on demand. You can transform objects as needed for your use case, such as redacting personally identifiable information (PII), enriching data with information from other sources, or converting between formats. Overview An Object Lambda handler is a small code module that transforms the contents of an object and returns the results. Like Amazon S3 Object Lambda functions, you trigger an AIStor Object Lambda handler function with a GET request from an application. The handler retrieves the requested object from AIStor, transforms it, and returns the modified data back to AIStor to send to the original application. The original object remains unchanged.

The MinIO Haskell Client SDK provides simple APIs to access MinIO and any Amazon S3 compatible object storage. This guide assumes that you have a working Haskell development environment. Installation Add to your project Simply add minio-hs to your project’s .cabal dependencies section or if you are using hpack, to your package.yaml file as usual.

Networking has the greatest impact on AIStor Server performance. Low per-host bandwidth artificially constrains the potential performance of the storage. MinIO recommends high speed networking to support the maximum possible throughput of the attached storage (aggregated drives, storage controllers, and PCIe busses). For best performance, use 100GbE or higher networking infrastructure. The following table provides a general guideline for the maximum storage throughput supported by a given physical or virtual network interface. This table assumes all network infrastructure components, such as routers, switches, and physical cabling, also supports the NIC bandwidth.

Generate temporary S3 credentials using Active Directory or LDAP user credentials with the AIStor STS AssumeRoleWithLDAPIdentity API.

Memory primarily constrains the number of concurrent simultaneous connections per node. MinIO recommends at least 256GiB of RAM per host. AIStor allocates up to 75% of host memory to support GET operations. Ensure you size your host memory such that the remaining available host memory supports your target number of concurrent connections per host. You can calculate the maximum number of concurrent requests per node with this formula: $$(0.75 * totalRam) / ramPerRequest$$ramPerRequest is typically 2MiB, which is two times the default erasure block size. For questions about adjusting the erasure block size for your use case, create a SUBNET issue to discuss with MinIO engineers.

Added in Operator RELEASE.2025-10-16T16-46-38Z Spread zone configuration requires Operator version RELEASE.2025-10-16T16-46-38Z or later. Spread zone configuration ensures that AIStor distributes Pods across configured zones to optimize availability and resiliency in the event any single worker node fails. Overview The Operator supports spread zone configuration by allowing you to specify zones in the topology of your cluster at the pool level.

The MinIO JavaScript Client SDK provides high level APIs to access any Amazon S3 compatible object storage server. This guide will show you how to install the client SDK and execute an example JavaScript program. For a complete list of APIs and examples, please take a look at the JavaScript Client API Reference documentation. This document presumes you have a working Node.js development environment, LTS versions v16, v18 or v20.

This page documents environment variables for configuring AIStor to publish data to an HTTP webhook endpoint and trigger an Object Lambda function. See Transforms with Object Lambda for more complete documentation and tutorials on using these environment variables. Environment Variables You can specify multiple targets by appending a unique identifier _ID for each set of related settings.

The mc version info command returns the versioning status for the specified bucket. Syntax Example The following command returns the versioning status for the mybucket bucket on the myaistor AIStor deployment:
